opchain

skills that ship.

A coordinated set of Claude skills covering the full software development pipeline — discover, spec, design, build, audit, ship, scale. One skill per phase. A shared JSON checkpoint protocol carries context across sessions and skills, so work resumes where you left off.

install

Claude Code — plugin (recommended)

Ships the skills plus the hooks that enforce them: a commit gate bound to the code being committed, pipeline state at session start, and a pointer to the next skill when one finishes.

/plugin marketplace add asfbay-bit/opchain-skills
/plugin install opchain

Claude Code — zip (skills only, no hooks)

curl -L https://opchain.dev/opchain-skills.zip -o opchain-skills.zip
unzip opchain-skills.zip -d .claude/skills/

the checkpoint protocol

Every skill writes a JSON checkpoint to .checkpoints/ in your project. Skills read each other's checkpoints to make informed decisions — context flows forward without manual handoffs.

oc-deploy-ops reads oc-code-auditor — CRITICAL findings block deploy
The build evaluator reads oc-ux-engineer — grades frontend against the approved design spec
oc-git-ops reads oc-app-architect — names branches by sprint

Schema lives in skills/oc-checkpoint-protocol/SKILL.md.

this repository

This is a public, force-push snapshot mirror of the skill source. The site, build system, and internal tooling live in a private upstream repo; only the product (this directory) is published here, refreshed on every change to main upstream.

See CONTRIBUTING.md for how issues and PRs flow back into the upstream repo.
